Stumped on the install

Hey gang heres my situation.
Dell 1400 with Adaptec AIC-7899 (39160) card and 2 quantum 18 gig drives.
512 megs of ram and a 800P3.
I went through the install guide and it went no sweat. After I was done I
typed halt (instead of reboot) So I cycled the machine and It doesn't boot.
I get a message that says Using Drive: 0 Partition: 3
and then it just sits there and never boots. I am stuck!
Thanks
Jamie
